A bill for an act relating to the nomination of candidates for president of the United States by political parties.

HF 484 allows Iowa political parties to choose between holding a presidential primary election or a caucus to select their presidential nominee. If a party opts for a primary, it must be held at least four days earlier than the initial nomination event in any other state or territory. Candidates must submit nomination petitions following existing rules, and the state elections commissioner will create implementing rules. The bill provides an alternative process but does not require parties to use primaries instead of caucuses.
